The widow of a limousine driver involved in a New York state crash that killed 20 people says her husband had expressed concerns about the company’s vehicles.

Kim Lisinicchia told CBS in an interview broadcast on Wednesday that there were several times she heard her husband, Scott, state: “I’m not going to drive this, like this. You need to get me another car.” But then “he trusted in what the limo company said, that the cars were all right.”

Lisinicchia was driving the limousine that ran through a stop sign Saturday at the bottom of a T-intersection on a rural road in Schoharie, 25 miles west of Albany. The crash killed two pedestrians and all 18 people in the limo celebrating a woman’s birthday. The driver was among the dead.

State police and the National Transportation Safety Board are investigating the cause of the crash, the nation’s deadliest transportation collision since Colgan Air Flight 3407 went down outside Buffalo in February 2009, killing 50 people.

Prestige Limousine has been criticized for maintaining vehicles rife with violations and for employing a driver lacking a commercial license.

Prestige’s lawyer, Lee Kindlon, has said that safety issues were corrected. He said the driver might have misjudged his ability to stop at the bottom of a hill.

But the driver’s wife took issue with that.

“He was in excellent health. He was an excellent driver. For over 20-plus years he drove a tractor trailer,” Kim Lisinicchia said.

“I feel for these victims,” she said. “I am in no way trying to make it seem like it’s about me or my husband. I just want my husband to be vindicated. I have to stand for him, ‘cause nobody else will.”

A statement issued previously through the Lisinicchia family’s lawyer said he would never have “knowingly put others in harm’s way.”

“The family believes that unbeknownst to him he was provided with a vehicle that was neither roadworthy nor safe for any of its occupants,” it said.

The limousine that ran the stop sign was cited for code violations on Sept. 4, including a problem with the antilock brakes’ malfunction indicator system. Four of the Gansevoort, New York-based company’s limos were cited for 22 maintenance violations this year, though none was deemed critical.

“Those safety issues had been addressed and corrected,” Kindlon told CBS News in a segment on Tuesday. “Not all infractions are major. A lot of these things are minor and were fixed.”

State Department of Transportation spokesman Joseph Morrissey said a sticker was placed on the vehicle after the September inspection declaring it “unserviceable.” He said Kindlon’s assertion that the code violations had been corrected and the vehicle cleared for service was “categorically false.”

Even if the repairs were made, the limo would have needed to be re-inspected and the owner would need approval again to transport passengers, a state transportation department spokesman said.

Kindlon said he doesn’t think those infractions contributed to the crash.

A vigil for the victims will be held on Wednesday evening in a Schoharie school gymnasium.

Services have been set for some of the victims, including 24-year-old Savannah Devonne Bursese, of Johnstown, the accident’s youngest victim. Her family is holding a private service Friday. In nearby Amsterdam, a funeral Mass is scheduled Saturday for the four King sisters, three of their husbands and the brother of one of the husbands.
